III. Transport
Label the parts of a phospholipid: (polar, nonpolar, phosphate, lipid, hydrophilic, hydrophobic)
[pic]
Label the parts of a bilayer: (polar, nonpolar, phosphate, lipid, hydrophilic, hydrophobic)
[pic]
Use the drawing below to indicate the location of inside the cell, outside of the cell, polar and nonpolar
[pic]
Using the image of a cell membrane below:
Color the proteins red Color the polar part green
Color the non polar part yellow Add in a channel (transport) protein.
Add in a carbohydrate marker on one of the proteins
[pic]
When we say that a lipid bilayer is semipermeable, what do we mean?
| |Passive transport |Active Transport |
|Requires energy | | |
|Moves molecules | |From low concentration to high concentration |
|Moves molecules |With (down) the concentration gradient | |
Define osmosis:
Label the following drawings as hypotonic, isotonic and hypertonic and draw an arrow to indicate the direction water will move. (The cell membrane is semipermeable but will not allow the particles to move thru…only water)
